Abstract
An ultrasound diagnostic apparatusincludes a transducer array, a transmission unitthat transmits a set of a first ultrasonic pulse FP and a second ultrasonic pulse SP having phases inverted from each other on the same scanning line from the transducer arrayinto a subject N times to be equal to or greater than at least two times, a reception unitthat acquires reception signals from a signal output from the transducer array, which receives an ultrasound echo, a quadrature detection unitthat acquires an IQ signal string corresponding to the first ultrasonic pulse FP and an IQ signal string corresponding to the second ultrasonic pulse SP by performing quadrature detection in a determined range on the reception signals, and a bubble signal likelihood calculation unitthat calculates a bubble signal likelihood based on the IQ signal strings acquired by the quadrature detection unit
